Multiscale Modeling in High Frequency Electromagnetics

Application ID: 43351

Multiscale modeling is a challenging issue in modern simulation. This occurs when there are vastly different scales in the same model. For example, your cell phone is approximately 10 cm, yet it receives GPS information from satellites 20,000 km away.

In these models we examine several multiscale solutions in COMSOL Multiphysics, all related to the problem of antenna to antenna communications over large distances. These models demonstrate coupling between the Electromagnetic Waves, Frequency Domain interface and both the Electromagnetic Waves, Beam Envelopes and Geometrical Optics interfaces.

The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
